The kasan functions that populates the shadow regions used to allocate them
page by page and did not take advantage of hugepages, so fix this by
trying to allocate hugepages of 1GB and fallback to 2MB hugepages or 4K
pages in case it fails.
This reduces the page table memory consumption and improves TLB usage,
as shown below:

Current population code populates a whole page table without taking care
of what could have been already allocated and without taking into account
possible index in page table, assuming the virtual address to map is always
aligned on the page table size, which, for example, won't be the case when
the kernel will get pushed to the end of the address space.
Address those problems by rewriting the kasan population function,
splitting it into subfunctions for each different page table level.

At early boot stage, we have a whole PGDIR to map the kernel, so there
is no need to restrict the early mapping size to 128MB. Removing this
define also allows us to simplify some compile time logic.
This fixes large kernel mappings with a size greater than 128MB, as it
is the case for syzbot kernels whose size was just ~130MB.
Note that on rv64, for now, we are then limited to PGDIR size for early
mapping as we can't use PGD mappings (see [1]). That should be enough
given the relative small size of syzbot kernels compared to PGDIR_SIZE
which is 1GB.

We use the generic C VDSO implementations of a handful of clock-related
functions. When kasan is enabled this results in asan stub calls that
are unlikely to be resolved by userspace, this just disables KASAN
when building the VDSO.
Verified the fix on a kernel with KASAN enabled using vDSO selftests.

The nommu_k210_defconfig default configuration allows booting a Canaan
Kendryte K210 SoC based boards using an embedded intramfs cpio file.
Modifying this configuration to enable support for the board SD card is
not trivial for all users. To help beginners getting started with these
boards, add the nommu_k210_sdcard_defconfig default configuration file
to set all configuration options necessary to use the board mmc-spi sd
card for the root file system.
This new configuration adds support for the block layer, the mmc-spi
driver and modifies the boot options to specify the rootfs device as
mmcblk0p1 (first partition of the sd card block device). The ext2 file
system is selected by default to encourage its use as that results in
only about 4KB added to the kernel image size. As ext2 does not have
journaling, the boot options specify a read-only mount of the file
system. Similarly to the smaller nommu_k210_defconfig, this new default
configuration disables virtual terminal support to reduce the kernel
image size.
The default device tree selected is unchanged, specifying the simple
"k210_generic" device tree file. The user must change this setting to
specify the device tree suitable for the board being used
(sipeed_maix_bit, sipeed_maix_dock, sipeed_maix_go, sipeed_maixduino or
canaan_kd233).

(nommu_k210_defconfig) to include device drivers for reset, reboot,
I2C, SPI, gpio and LEDs support. Virtual Terminal support is also
disabled as no terminal devices are supported and enabled. Disabling
CONFIG_VT (removing the no longer needed override for
CONFIG_VGA_CONSOLE) reduces the kernel image size by about 65 KB.
This default configuration remains suitable for a system using an
initramfs cpio file linked into the kernel image.

Update the Canaan Kendryte K210 base device tree k210.dtsi to define
all supported peripherals of the SoC, their clocks and reset lines.
The device tree file k210.dts is renamed to k210_generic.dts and
becomes the default value selection of the configuration option
SOC_CANAAN_K210_DTB_BUILTIN_SOURCE. No device beside the serial console
is defined by this device tree. This makes this generic device tree
suitable for use with a builtin initramfs with all known K210 based
boards.
These changes result in the K210_CLK_ACLK clock ID to be unused and
removed from the dt-bindings k210-clk.h header file.
Most updates to the k210.dtsi file come from Sean Anderson's work on
U-Boot support for the K210.

Pull documentation updates from Jonathan Corbet:
"It has been a relatively quiet cycle in docsland.
- As promised, the minimum Sphinx version to build the docs is now
1.7, and we have dropped support for Python 2 entirely. That
allowed the removal of a bunch of compatibility code.
- A set of treewide warning fixups from Mauro that I applied after it
became clear nobody else was going to deal with them.
- The automarkup mechanism can now create cross-references from
relative paths to RST files.
- More translations, typo fixes, and warning fixes"

Track the range being invalidated by mmu_notifier and skip page fault
retries if the fault address is not affected by the in-progress
invalidation. Handle concurrent invalidations by finding the minimal
range which includes all ranges being invalidated. Although the combined
range may include unrelated addresses and cannot be shrunk as individual
invalidation operations complete, it is unlikely the marginal gains of
proper range tracking are worth the additional complexity.
The primary benefit of this change is the reduction in the likelihood of
extreme latency when handing a page fault due to another thread having
been preempted while modifying host virtual addresses.

Don't retry a page fault due to an mmu_notifier invalidation when
handling a page fault for a GPA that did not resolve to a memslot, i.e.
an MMIO page fault. Invalidations from the mmu_notifier signal a change
in a host virtual address (HVA) mapping; without a memslot, there is no
HVA and thus no possibility that the invalidation is relevant to the
page fault being handled.
Note, the MMIO vs. memslot generation checks handle the case where a
pending memslot will create a memslot overlapping the faulting GPA. The
mmu_notifier checks are orthogonal to memslot updates.

Right now, enter_svm_guest_mode is calling nested_prepare_vmcb_save and
nested_prepare_vmcb_control. This results in is_guest_mode being false
until the end of nested_prepare_vmcb_control.
This is a problem because nested_prepare_vmcb_save can in turn cause
changes to the intercepts and these have to be applied to the "host VMCB"
(stored in svm->nested.hsave) and then merged with the VMCB12 intercepts
into svm->vmcb.
In particular, without this change we forget to set the CR0 read and CR0
write intercepts when running a real mode L2 guest with NPT disabled.
The guest is therefore able to see the CR0.PG bit that KVM sets to
enable "paged real mode". This patch fixes the svm.flat mode_switch
test case with npt=0. There are no other problematic calls in
nested_prepare_vmcb_save.
Moving is_guest_mode to the end is done since commit 06fc7772690d
("KVM: SVM: Activate nested state only when guest state is complete",
2010-04-25). However, back then KVM didn't grab a different VMCB
when updating the intercepts, it had already copied/merged L1's stuff
to L0's VMCB, and then updated L0's VMCB regardless of is_nested().
Later recalc_intercepts was introduced in commit 384c63684397
("KVM: SVM: Add function to recalculate intercept masks", 2011-01-12).
This introduced the bug, because recalc_intercepts now throws away
the intercept manipulations that svm_set_cr0 had done in the meanwhile
to svm->vmcb.

The rules in these Makefiles cannot detect the command line change
because the prerequisite 'FORCE' is missing.
Adding 'FORCE' will result in the headers being rebuilt every time
because the 'targets' additions are also wrong; the file paths in
'targets' must be relative to the current Makefile.
Fix all of them so the if_changed rules work correctly.

- Support for userspace to emulate Xen hypercalls
- Raise the maximum number of user memslots
- Scalability improvements for the new MMU. Instead of the complex
"fast page fault" logic that is used in mmu.c, tdp_mmu.c uses an
rwlock so that page faults are concurrent, but the code that can run
against page faults is limited. Right now only page faults take the
lock for reading; in the future this will be extended to some
cases of page table destruction. I hope to switch the default MMU
around 5.12-rc3 (some testing was delayed due to Chinese New Year).
- Cleanups for MAXPHYADDR checks

- On AMD, use VMLOAD/VMSAVE to save and restore host state
